CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0019306, filed on Feb. 19, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein its entirety.

BACKGROUND 1. Field

The disclosure relates to a technology of processing a user input, in particular, a user utterance.

2. Description of Related Art

In addition to a conventional input method using a keyboard or a mouse, electronic devices have recently supported various input schemes such as a voice input and the like. For example, the electronic devices such as smart phones or tablet PCs may receive a user voice and then may provide a service that performs an operation corresponding to the entered user voice.

The speech recognition service is being developed based on a technology for processing a natural language. The technology for processing a natural language refers to a technology that grasps the intent of a user input (utterance) and generates the result matched with the intent to provide the user with the service.

In the meantime, while the chatting mode using the user utterance is executed, it may be difficult for the electronic device to provide appropriate responses to all user inputs. In particular, when a user input that is difficult for the electronic device to recognize is entered, the electronic device has no choice but to provide an ambiguous response.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

When the electronic device receives an ambiguous user input while executing a chatting mode using user utterance, the electronic device may provide a user with a response for terminating the conversation not associated with the user input. This makes it difficult for the electronic device and the user to talk to each other continuously.

Furthermore, when purposeless utterance is entered as a user input, the electronic device may not accurately grasp the intent of the user input and may provide the user with a response not corresponding to the user input.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device and a system that are capable of providing the user with an appropriate response even though ambiguous or purposeless utterance is entered, by providing the user with response data from the database classified based on a category.

In accordance with an aspect of the disclosure, an electronic device may include a user interface, a processor operatively coupled to the user interface, and a memory operatively coupled to the processor. The memory may be configured to store a main database including at least one input data and/or an auxiliary database including at least one category including pieces of response data. The memory may store instructions that, when executed, cause the processor to receive a user input, using the user interface, to extract first information from the user input, to identify the input data of the main database matched with the first information, to identify a category of the user input based on an event that the input data of the main database matched with the first information is not identified, to identify the auxiliary database corresponding to the category, and to provide first response data based on an event that the auxiliary database is identified.

In accordance with another aspect of the disclosure, a method may include receiving the user input, using a user interface, extracting first information from the user input, identifying input data of a main database matched with the first information, identifying a category of the user input based on an event that the input data of the main database matched with the first information is not identified, identifying an auxiliary database corresponding to the category, and providing first response databased on an event that the auxiliary database is identified.

In accordance with another aspect of the disclosure, a system may include a first electronic device including a communication module and a user interface and a second electronic device communicating with the first electronic device through the communication module and including a processor and a memory operatively coupled to the processor. The memory may be configured to store a main database including at least one input data and/or an auxiliary database including at least one category including pieces of response data. The memory may store instructions that, when executed, cause the processor to receive a user input entered to the first electronic device using the user interface, from the first electronic device, to extract first information from the user input, to identify the input data of the main database matched with the first information, to identify a category of the user input based on an event that the input data of the main database matched with the first information is not identified, to identify the auxiliary database corresponding to the category, and to transmit first response data to the first electronic device based on an event that the auxiliary database is identified.

The first electronic device 500 may further include at least one of additional components in addition to the components illustrated in FIG. 5. According to an embodiment, the components of the first electronic device 500 may be the same entities or may constitute separate entities.

For example, the first electronic device 500 may include a smartphone, a tablet PC, a wearable device, a home appliance, or a digital camera.

According to an embodiment, the processor 520 may be operatively coupled to the communication module 590, the memory 530, and the user interface (the microphone 550 and the speaker 555) to perform overall functions of the first electronic device 500. For example, the processor 520 may include one or more processors. For example, one or more processors may include an image signal processor (ISP), an application processor (AP), or a communication processor (CP).

Modules described in various embodiments of the disclosure may be implemented by hardware or software.

The first electronic device 500 may receive a user input by using a user interface.

In an embodiment, the user input may be a user's voice input (e.g., utterance). When the user input is a voice input, the first electronic device 500 may receive a user input through the microphone 550.

In an embodiment, the user input may be the user's text input. When the user input is a text input, the first electronic device 500 may receive a user input through an input device (e.g., the input device 750 of FIG. 4).

The processor 520 may be configured to transmit a user input to the second electronic device 600, using the communication module 590. When receiving response data corresponding to the user input from the second electronic device 600 through the communication module 590, the processor 520 may allow the response data to be output through a speaker 555.

The memory 530 may store a main database 670 including at least one input data and/or an auxiliary database 680 including at least one category including pieces of response data. The memory 530 may store commands, information, or data associated with operations of components included in the first electronic device 500. For example, the memory 530 may store instructions, when executed, that cause the processor 520 to perform various operations described in the disclosure.

The second electronic device 600 may include a processor 601, an ASR module 610 (e.g., the ASR module 221 of FIG. 1), a first NLU module 621 (e.g., the NLU module 223 of FIG. 1), a second NLU module 622, a TTS module 660 (e.g., the TTS module 229 of FIG. 1), a memory 603, the main database 670, the auxiliary database 680, a planner module 625 (e.g., the planner module 225 of FIG. 1), and an analysis module 605.

The second electronic device 600 may further include at least one of additional components in addition to the components illustrated in FIG. 5. For example, the second electronic device 600 may include a communication module or a connecting terminal for communicating with the first electronic device 500. According to an embodiment, the components of the second electronic device 600 may be the same entities or may constitute separate entities.

The processor 601 may drive the ASR module 610, the first NLU module 621, the second NLU module 622, the analysis module 605, the planner module 625, and the TTS module 660 by executing the instructions stored in the memory 603. The processor 601 may be operatively coupled to the ASR module 610, the first NLU module 621, the second NLU module 622, the analysis module 605, the planner module 625, and the TTS module 660 to perform overall functions of the second electronic device 600. In the embodiment disclosed in this specification, it may be understood that the operation performed (or executed) by the ASR module 610, the first NLU module 621, the second NLU module 622, the analysis module 605, the planner module 625, and the TTS module 660 is an operation performed by the processor 601 executing instructions stored in the memory 603.

The memory 603 may store commands, information, or data associated with operations of components included in the second electronic device 600. For example, the memory 603 may store instructions, when executed, that cause the processor 601 to perform various operations described in the present disclosure.

In an embodiment, unlike the illustration of FIG. 5, the processor 601 may include the ASR module 610, the first NLU module 621, the second NLU module 622, the analysis module 605, the planner module 625, and the TTS module 660. In this case, the operation performed (or executed) by each of the ASR module 610, the first NLU module 621, the second NLU module 622, the analysis module 605, the planner module 625, and the TTS module 660 may be implemented as at least part of the processor 601.

In an embodiment, the second NLU module 622 may include the analysis module 605. The operation performed (or executed) by the analysis module 605 may be implemented as a part of the second NLU module 622.

In an embodiment, the second electronic device 600 may receive a user input from the first electronic device 500. For example, the user input may be a user utterance.

The ASR module 610 may convert the received user input into text data.

The first NLU module 621 may determine user intent by performing grammatical analysis or semantic analysis on the user input. The planner module 625 may generate the plan, using the intent and the parameter, which are determined by the first NLU module 621. According to an embodiment, the planner module 625 may determine one or more domains necessary to perform a task, based on the determined intent. For example, the planner module 625 may grasp that a user desires to execute a capsule or domain (e.g., chat bot) supporting the chatting mode using an utterance, based on a user input.

The second NLU module 622 may extract first information from the user input by perform grammatical analysis or semantic analysis. For example, the first information may include a parameter (or slot) required to represent the user intent, the domain, or the intent, a word included in a user input, and the part of speech corresponding to the word included in the user input. In an embodiment, the second NLU module 622 may be executed in the capsule or domain. For example, the capsule or domain may be a chat domain, a weather domain, a music domain, or a third party domain, but the embodiments disclosed in this specification are not limited thereto.

The second NLU module 622 may identify the input data of the main database 670 matched with the first information, based on the first information. Weight information may be included in the first information based on the event that the second NLU module 622 identifies the input data of the main database 670 matched with the first information. For example, the weight information may indicate the extent to which the first information is matched with the input data of the main database 670.

The main database 670 may include an input data set and a response data set corresponding to the input data. The input data set may include pieces of input data capable of being matched with a user input (e.g., the first information). The response data set may include pieces of response data corresponding to the input data. For example, when the user input is matched with first input data in the input data set of the main database 670, the processor 601 or the second NLU module 622 may output first response data corresponding to the first input data from the main database 670.

The analysis module 605 may identify the category of the user input based on the event that the input data of the main database 670 matched with the first information is not identified. The category may include, for example, affirmative, negative, completion, family, and love categories, but the embodiments disclosed in this specification are not limited thereto.

In an embodiment, the case where the input data of the main database 670 matched with the first information is not identified may be the case where the input data capable of being matched with the first information is present in the main database 670 but the weight is less than a reference weight. For example, when the weight is less than a reference weight, the extent to which the first information is matched with the first input data may be low. In this case, when the first response data corresponding to the first input data is output to a user, the user may recognize that the first electronic device 500 does not give a proper response to the user input.

In an embodiment, the case where the input data of the main database 670 matched with the first information is not identified may be the case where the input data matched with the first information is not included in the input data set of the main database 670. In an embodiment, the case where the input data of the main database 670 matched with the first information is not identified may be the case where the input data matched with the first information is difficult to be specified in the input data set of the main database 670.

When the input data of the main database 670 matched with the first information is not identified, the second NLU module 622 may not output response data in the main database 670 and may deliver the user input to the analysis module 605.

In an embodiment, when the analysis module 605 is implemented in the second NLU module 622, the second NLU module 622 may not output the response data from the main database 670 and may identify the category of the user input.

For example, the analysis module 605 may extract second information from the user input. For example, the second information may include a word included in the user input and information of the part of speech corresponding to the word. For example, the second information may include keyword information, such as, a string included in the user input. For example, unlike the first information, the second information may not include weight information.

The analysis module 605 may identify the category of the user input based on the second information. The analysis module 605 may identify the auxiliary database 680 corresponding to the identified category.

For example, the auxiliary database 680 may include one or more databases including a response data set for each category. For example, the response data set may include pieces of response data. For example, the auxiliary database 680 may include ‘n’ category DBs (‘n’ is a natural number). When each category DB is identified as the category corresponding to the user input, each category DB may include a response data set to be provided. For example, the auxiliary database 680 may include a first category DB corresponding to a complete category and a second category DB corresponding to a family category. When the user input is identified as the complete category, the analysis module 605 may identify the first category DB being the auxiliary database 680.

The analysis module 605 may provide response data from the auxiliary database 680, based on the event that the auxiliary database 680 (e.g., the first category DB) is identified. For example, the analysis module 605 may output single response data among pieces of response data included in the auxiliary database 680 (e.g., the first category DB).

In an embodiment, the auxiliary database 680 may include the response data set corresponding to the category not included in the main database 670. For example, when the input data matched with the first information is not included in the input data set of the main database 670, the electronic device according to an embodiment disclosed in the specification may provide the user with the response data in the auxiliary database 680.

In an embodiment, the auxiliary database 680 may include the response data set corresponding to the category included in the main database 670. For example, when the input data matched with the first information is present in the input data set of the main database 670 but the weight is less than the reference weight or it is difficult to specify response data, the electronic device according to an embodiment disclosed in the specification may provide the user with the response data in the auxiliary database 680.

The TTS module 660 may convert the response data being in a text form into voice data. The second electronic device 600 may transmit the response data converted into the voice data, to the first electronic device 500. The first electronic device 500 and/or the processor 520 may output the response data converted into the voice data, through the speaker 555.

In an embodiment, the operations of each component described with reference to the second electronic device 600 may be performed (or executed) by the first electronic device 500.

In an embodiment, the category DB of the auxiliary database 680 may further include a sub category DB. When the phrases associated with emotion is included in the user input, after identifying the category DB, the electronic device may identify the sub category DB based on the phrase associated with the emotion. For example, the second information may include information indicating that the phrase associated with the emotion is included. The electronic device may output the response data corresponding to user input in the sub category DB.

Hereinafter, a method in which an electronic device according to an embodiment disclosed in the specification processes a user input will be described with reference to FIG. 6.

FIG. 6 illustrates a sequence diagram 60 for describing a method of providing response data corresponding to a user input of an electronic device according to an embodiment disclosed in the specification. For clarity of descriptions, contents the same as the above-described details are briefly described or omitted.

Hereinafter, it is assumed that the first electronic device 500 and the second electronic device 600 of FIG. 5 perform the process of FIG. 6. The operation described as being performed by the first electronic device 500 and the second electronic device 600 may be implemented using instructions capable of being performed (or executed) by each of the processor 520 of the first electronic device 500 and the processor 601 of the second electronic device 600. For example, the instructions capable of being performed (or executed) by the processor 520 may be stored in a computer-readable recording medium or the memory 530 of the first electronic device 500 illustrated in FIG. 5. For example, the instructions capable of being performed (or executed) by the processor 601 may be stored in a computer-readable recording medium or the memory 603 of the second electronic device 600 illustrated in FIG. 5.

Referring to FIGS. 5 and 6, in operation 1001, the first electronic device 500 may receive a user input. For example, the user input may be a user's voice input. For example, the user may enter a voice, using the microphone 550 of the first electronic device 500.

In operation 1003, the first electronic device 500 may transmit a user input to the second electronic device 600. For example, the first electronic device 500 may transmit the user input, using the communication module 590.

In operation 1005, the second electronic device 600 may extract first information from the user input. For example, the second electronic device 600 may extract the first information from the user input based on natural language processing.

In operation 1007, the second electronic device 600 may identify the input data of the main database 670 matched with the first information. For example, the second electronic device 600 may access the main database 670 to search for the input data matched with the first information.

In operation 1008, the second electronic device 600 may identify the category of the user input based on the event that the input data of the main database 670 matched with the first information is not identified. When the extent to which the first information is matched with the input data is low or when the input data matched with the first information is not present in the main database 670, the second electronic device 600 may not output the response data in the main database 670.

In operation 1009, the second electronic device 600 may identify the auxiliary database 680 corresponding to the identified category. The second electronic device 600 may identify which category DB the user input corresponds to, in the category DB included in the auxiliary database 680. For example, the second electronic device 600 may identify the category DB corresponding to the category of the user input, in ‘n’ category DBs (‘n’ is a natural number) included in the auxiliary database 680.

In operation 1011, the second electronic device 600 may output the response data based on the event that the auxiliary database 680 is identified. For example, the identified auxiliary database 680 (i.e., one in the category DB) may include a response data set. The second electronic device 600 may provide the single response data in the response data set included in the identified auxiliary database 680.

In operation 1013, the second electronic device 600 may transmit the response data to the first electronic device 500. The response data output from the auxiliary database 680 may be in a text form. The second electronic device 600 may convert the response data being in the text form into voice data to transmit the voice data to the first electronic device 500.

In operation 1015, the first electronic device 500 may output the response data received from the second electronic device 600. For example, the first electronic device 500 may output the response data received as the voice data, through the speaker 555.

Hereinafter, a method in which an electronic device according to an embodiment disclosed in the specification processes a user input will be described with reference to FIGS. 7, 8A, 8B, and 8C.

FIG. 7 illustrates a flowchart 70 for describing an operation method in which an electronic device processes a user input, according to an embodiment disclosed in the specification. FIG. 8A illustrates a view 81 for describing a user input and response data, according to an embodiment disclosed in the specification. FIG. 8B illustrates a view 82 for describing a user input and a category, according to an embodiment disclosed in the specification. FIG. 8C illustrates a view 83 for describing an auxiliary database and response data, according to an embodiment disclosed in the specification. For clarity of descriptions, contents the same as the above-described details are briefly described or omitted.

Hereinafter, it is assumed that one of the first electronic device 500 or the second electronic device 600 of FIG. 5 performs the process of FIG. 7. The operation described as being performed by one of the first electronic device 500 or the second electronic device 600 may be implemented with instructions capable of being performed (or executed) by a processor (e.g., one of the processor 520 or the processor 601). For example, the instructions capable of being performed (or executed) by a processor may be stored in a computer-readable recording medium or a memory (e.g., one of the memory 530 or the memory 603).

Referring to FIG. 7, in operation 2001, the electronic device may receive a user input. For example, the user input may be a user's voice input. In an embodiment, the electronic device may receive a user input from an external electronic device.

In operation 2003, the electronic device may determine a domain supporting a chatting mode and may process the determined domain-based response. The electronic device may grasp a user's intent from the user input. The electronic device may determine the domain based on the user input and may grasp that the user desires to process a domain or application (chat bot)-based response supporting the chatting mode using an utterance.

Referring to FIG. 8A, the user may enter voice data saying that “what am I doing tomorrow?” as a first input U1. The electronic device may grasp the user's intent by performing grammatical analysis or semantic analysis on the first input U1. In the exemplification that the first input U1 is “what am I doing tomorrow?”, the electronic device may grasp the intent that the user desires to talk to the electronic device. For example, the electronic device may grasp the user's intent by identifying that the intent for performing a specific task (e.g., sending a message, making a call, or executing a specific application) is not included in the first input U1. For example, in the exemplification that the first input U1 is “what am I doing tomorrow?”, the electronic device may identify that the first input U1 is a purposeless utterance.

Referring to FIG. 7, in operation 2005, the electronic device may extract the first information from the user input. For example, the first information may be information for performing matching with pieces of input data included in a main database (e.g., the main database 670 of FIG. 5).

In the first input U1 of FIG. 8A, the electronic device may extract a word included in the first input U1, the part of speech corresponding to the word, the user's intent, and a parameter (or slot) necessary to represent the user's intent, as the first information.

Returning to FIG. 7, in operation 2007, the electronic device may identify the input data of the main database matched with the first information. For example, the main database may include an input data set and a response data set corresponding to the input data. The electronic device may access the main database and may match the first information with each of the pieces of input data included in the input data set. The input data set may include an example list of the user inputs that are expected to be entered by the user. The response data set may include pieces of response data respectively corresponding to the pieces of input data included in the input data set.

In operation 2009, the electronic device may output response data corresponding to the user input in the main database based on the event that the input data of the main database matched with the first information is identified.

In an embodiment, when the response data is in a text form, the electronic device may convert the response data into voice data to transmit the voice data to an external electronic device. For example, the external electronic device may output the response data that is voice data.

Returning to FIG. 8A, the first information about the first input U1 may be matched with the input data included in, for example, the input data set of the main database. The electronic device may output the first response data A1 corresponding to the matched input data, from the main database. For example, the response data corresponding to the matched input data may be a response data set including pieces of response data. The first response data A1 may be one of the pieces of response data.

For example, the electronic device may output the first response data A1 saying that “make a bucket list you want at this chance” with respect to the first input U1. The first response data A1 that is in the text form may be converted into voice data and then the voice data may be provided to the user in a voice form.

Referring to FIG. 7, in operation 2011, the electronic device may identify the category of the user input, based on the event that the input data of the main database matched with the first information is not identified. For example, the electronic device may extract the second information from a user input to identify the category of the user input. For example, the second information may be information for performing matching with category DBs included in the auxiliary database (e.g., the auxiliary database 680 of FIG. 5).

Returning to FIGS. 7 and 8A together, the electronic device may receive a second input U2 saying that “already done” from the user. The electronic device may identify that the intent for performing a specific task is not included in the second input U2. In operation 2003, the electronic device may identify the user still desires to execute a capsule or domain supporting a chatting mode, by grasping the user intent for the second input. In operation 2005, the electronic device may extract the first information from the second input U2. In operation 2007, the electronic device may identify the input data of the main database matched with the first information about the second input U2. In the exemplification that the second input U2 is “already done”, the input data of the main database matched with the first information about the second input U2 may not be identified. In operation 2011, the electronic device may identify the category of the second input U2.

Referring to FIG. 8B, the electronic device may extract second information based on the string or word of the second input U2 of “already done”. The electronic device may access the auxiliary database to match the second information with the input data set of the auxiliary database. For example, the electronic device may match the second information with the pieces of input data included in each of the first input data set DS1 and the second input data set DS2. The electronic device may identify that the second input is matched with the first input data set DS1, based on the second information. The electronic device may identify the second input U2 as a first category (e.g., completion).

Returning to FIG. 7, in operation 2013, the electronic device may determine whether an auxiliary database corresponding to the category is identified.

In operation 2015, the electronic device may output response data from the auxiliary database, based on the event that the auxiliary database is identified.

Referring to FIG. 8C, for example, the auxiliary database may include ‘n’ category DBs 680-1, 680-2, 680-3, . . . , and 680-n (‘n’ is a natural number). Each category DB may include response data set including pieces of response data. For example, the first category DB 680-1 may include a response data set DR.

The electronic device may identify the first category DB 680-1 of the auxiliary database 680, based on the event that the second input U2 is identified as the first category. The first category DB 680-1 may include a response data set DR. The electronic device may output second response data A2 of FIG. 8A, which is one of response data sets DR of the first category DB 680-1. In the exemplification that the second input U2 is “already done”, the electronic device may identify the first category DB 680-1 that is a complete category and may output second response data A2 saying that “please tell me if you need anything more” in the response data set DR of the first category DB 680-1.

An electronic device according to embodiments disclosed in the specification may provide a user with an accurate response by outputting response data matched with a user input from the auxiliary database in response to the user input not capable of identifying response data in the main database.

Returning to FIG. 7, in operation 2017, the electronic device may output third response databased on the event that the auxiliary database corresponding to the category is not identified. For example, when the user input is not matched with pieces of data included in the main database and the auxiliary database, the electronic device may output the third response data. For example, the third response data may be data included in a database separate from the main database and the auxiliary database.

Hereinafter, a method in which an electronic device according to an embodiment disclosed in the specification processes a user input will be described with reference to FIGS. 8B, 9A, 9B, and 9C.

FIG. 9A illustrates a view 91 for describing a user input and response data, according to an embodiment disclosed in the specification. FIG. 9B illustrates a flowchart 93 for describing a method in which an electronic device processes a user input, according to an embodiment disclosed in the specification. FIG. 9C illustrates a view 92 for describing an auxiliary database and response data, according to an embodiment disclosed in the specification. For clarity of descriptions, contents the same as the above-described details are briefly described or omitted. Operation 2001, operation 2003, operation 2005, operation 2007, operation 2009, operation 2011, operation 2013, and operation 2017 of FIG. 9B may correspond to operation 2001, operation 2003, operation 2005, operation 2007, operation 2009, operation 2011, operation 2013, and operation 2017 of FIG. 7.

Referring to FIGS. 9A and 9B, the electronic device may perform operation 2001, operation 2003, operation 2005, and operation 2007 in response to the event that “I dislike mom”, which is the third input U3, is entered as a user input. In operation 2007, the electronic device may determine that the input data of the main database matched with the first information for the third input U3 is not identified. In an embodiment, the main database may not include a response data set for each of a word associated with a family and/or a word associated with negative (or positive) emotions.

In operation 2011, the electronic device may identify the category of the third input U3.

Referring to FIG. 8B, the electronic device may extract second information based on the string or word of the third input U3 of “I dislike mom”. For example, the electronic device may identify that the third input U3 is matched with the second input data set DS2, based on the second information. The electronic device may identify the third input U3 as a second category (e.g., family).

Returning to FIG. 9B, in operation 2013, the electronic device may determine whether an auxiliary database corresponding to the category is identified.

In operation 2016, the electronic device may determine a phrase associated with the emotion in the user input and may output the response data in the auxiliary database, based on the event that the auxiliary database is identified.

Referring to FIG. 9C, one of ‘n’ category DBs 680-1, 680-2, 680-3, . . . , and 680-n of the auxiliary database (‘n’ is a natural number) may include ‘m’ sub category DBs (‘m’ is a natural number).

In an embodiment, when the user input includes the phrase associated with emotions, such as the third input U3 (e.g., “dislike” associated with negative emotions is included in “I dislike mom”), the electronic device may access first to ‘m’ sub category DBs included in the second category DB 680-2.

In an embodiment, when the sentence in which there is no direct emotional expression but an emotion is capable of being detected is included, the electronic device may access the first to ‘m’ sub category DBs included in the second category DB 680-2. For example, the sentence in which there is no direct emotional expression but an emotion is capable of being detected may be implemented with a technology such as machine learning.

For example, a sub category DB may include a category of “positive”, “negative”, or “unknown”.

For example, the electronic device may identify that a phrase (e.g., mom) capable of being classified as a specific category and a phrase (e.g., dislike) associated with the emotion are included in the third input U3 or that the sentence capable of detecting emotions is included in the third input U3. The electronic device may identify the second category DB corresponding to the third input U3 and may identify a sub category DB of the second category corresponding to the phrase associated with the emotion. For example, the electronic device may output the third response data A3 from one of sub category DBs (e.g., the first sub category DB) of the second category DB.

An electronic device according to embodiments disclosed in the specification may provide a user with an accurate response by identifying the upper category and sub category from the auxiliary database to output response data matched with a user input from the sub category database in response to a user response including the phrase associated with an emotion not capable of outputting response data from the main database.
